Are you using Firefox? There seems no problems when using Firefox, try Chrome. Or just see the PDF docs, it's clearer.

You will find that the single quote sign in sentence "A Manager‘s base QuerySet returns all objects in the system" is not as same as in other sentences like "you’d use OpinionPoll.objects.with_counts() to return that list of OpinionPoll objects with num_responses attributes"(the second sentence is just above the first sentence).

You can find many same typos in PDF version of document, just search the single quote sign in sentence "A Manager‘s base QuerySet returns all objects in the system" in page 119.

Not all single quote signs are wrong, for the single quote sign in sentence "you’ll be logged in as the attacker and might inadvertently enter your sensitive personal data (e.g. credit card info) into the attackers account." in page 203 in PDF docs is right.

By the way, the single quote sign in sentence "*.example.com‘" in page 203 in PDF docs may be reduntant.
